Application 1115a June 13, 1892.

T0 aZZ whom it may concern.-

Be it known that I, JOHN WALKER, a subject of the Queen of Great Britain and Ireland, residing at Oldham, in the county of Lancaster, England, have invented Improvements in Apparatus for Spinning and Doubling Yarns, of which the following is a specification.

This invention relates to apparatus forspinning and doubling yarns made from cotton and other fibers.

The objects of the invention are to simplify, improve, and economize the construction and working of the apparatus and to produce a more even yarn than heretofore at a reduced expense.

The nature of the said invention and the manner in which the same is to be performed or carried into practical effect will be readily understood on reference to the drawings hereunto annexed and the following explanation thereof.

Figures 1 and 2 of the drawings are vertical transverse sections of so much of the improved spinning and doubling frame as is necessary to illustrate the invention and Figs. 3 and 4 are corresponding partial plan views. Fig. 5 is a partial front elevation, Fig. 6 a partial end view and Fig. 7 a partial plan View showing more particularly parts of the frame which are not shown on the other views in order to avoid confusion.

Theimproved apparatus is constructed as follows: On a frame a of suitable form I arrange the usual creel b, drawing rollers and stand 0 as in the mule, throstle, or ring spinning frame, placing them in about the ordi-v nary positions. At a convenient distance from the rollers c I place a right angled beam or rail (1 on which, at the ends and at other convenient points are fixed vertical slides e. These slides '6 Work in grooves f formed in or on the frame side and other requisite points, and fixed to the back of the beam d are projecting arms g carrying bearings in which revolves a shaft 7?. fitted with a tin drum 7:.

Along the front of the beam (1 and at regular distances according to the requirements,

holes are drilled and fitted if necessary with bushes, or bearings are provided in which re- Scrial No. 436,435. (No model.)

volve a series of metal disks 76 which work on a vertical axis and are each provided beneath with a grooved band pulley Z by means of which they are driven by endless bands from the tin drum 2' at the other side of the beam d. The disks 7c are bored through the center, and on the top of each is an upright arm or projection on with a curl at the top for the yarn to pass through; this is made a sufficient length to make a cop as required.

Under the beam cl (which I name the disk-beam) I place a horizontal double spindle rail n which is also mounted in vertical slides and is provided with racks 0 and wheels p to work it up and down and this double spindle rail n is balanced by weights and chains q hung over pulleys as seen at Fig. 1.

In the spindle rail n at exactly the same distance apart as the disks 70 are, and directly under each one of the latter there is a bearing and footstep for a spindle r to work in. The spindles r are fixed vertically in the rail n and pass through the centers of the disks it above (see Figs. 1, 2 and 5).

Behind the roller stand 0 in a convenient position is fixed the principal driving shaft .9 on which is keyed a spur wheel 25 (Fig. 3) driving a similar wheel u of smaller diameter on another shaft 1; on which there is a spur wheel w driving a smaller spur wheel 00 which is fixed or cast to a bevel wheel y revolving loose on the principal driving shaft 3 and gearing with a bevel pinion z.

From the principal driving shaft 8 to the tin drum shaft 1' carried by the disk beam d is fixed an arm or swing bracket Z in or on which are bearings supporting a shaft 2 which is driven by the aforesaid bevel wheel 'y and pinion 2' and works the tin roller shaft 71 by the bevel wheels 3, 3. There is a provision made for changing the wheels 3 so as to obtain any number of revolutions required for the speed of the disks. On the driving shaft 8 is also keyed a spur pinion 4 (see Figs 2 and 3) driving a second motion shaft 5 at a suitable speed by a wheel 6 and on this shaft 5 is an eccentric wheel 7 (Figs. 2 and 4) driving a similar wheel 8 on the first countershaft 9 and on this shaft is a heart shaped tappet or cam 10 which works a lever 11 swung at its center and having a bowl at one end under the cam and the other end working under a bowl carried by a bracket 12 attached to the disk-beam cl so as to give a varying rising and falling motion thereto. On the second motion shaft 5 there -is another eccentric wheel 13 driving a similar wheel 14 on the second counter-shaft 15 and on this is keyed a spur wheel 16 driving a lower shaft 17 by a pinion 18. On one end of this lower shaft 17 is a bevel wheel 19 (see Figs. 4, 5 and 6) driving by means of a smaller bevel wheel 20 the diagonal shaft 21 which actuates the rollers c by means of the miter wheels 22.

The rack wheels 19 for actuating the spindle rail n before mentioned are driven in the following manner. To the lever 11 (see Fig. 2) is attached a chain 23 passing over a pulley and having its other end connected to an arm 24 which carries a pawl 25 acting on a ratchet wheel 26 (see also Figs. 6 and 7) which is connected by a train of gearing 27 to the rack wheel 19. 28 is a lever fixed on a stud at one end and extending outside in front of the machine where it is formed in the shape of a handle. On this lever is an adjustable bracket 29 which supports the arm 24 carrying the pawl. Near the front of the machine is another adjustable bracket 30 upon which the lever 28 rests and when in this position the left hand side of the chain 23 is slack at first and a certain amount of lift is thus lost. On the rack 0 of the spindle rail is fixed an adjustable plate 31 with an incline on the side next the lever (see Fig. 5) and therefore as the spindle rail 91 descends the incline 31 pushes the lever 28 off the rest or bracket 30 and the pawl and ratchet give more lift as required. The pawl is a retaining catch for the ratchet wheel 26. The yarn of cotton or other fiber passes from the drawing rollers c to a curl or guide 32 (Fig. 2) fixed on the disk beam cl over the center of each spindle 'r' to the curl m on the disk 10 and through the latter to the spindle r or onto a bobbin or tube. The disk being driven as before stated by a band from the tin drum 1', revolves, carrying the yarn with it, and thus puts in a turn or twist at every revolution of the disk, and the yarn being carried round by the disk drags the spindle 1" round with it and causes that to revolve also so long as it is kept held hard by the yarn, and as the yarn is eased by the delivery of the drawing rollers c it becomes wound on the bare spindle, and the disk It being raised and lowered by the heart wheel or cam 10 the yarn is correspondingly placed on the spindle by the curl m on the disk. The eccentric wheels 7 and 8 on the second motion shaft 5 and the first countershaft 9 cause the heart wheel or cam 10 to have an alternate quick and slow speed in revolving. The heart wheel or cam 10 is so fixed on its shaft 9 that while its smaller radius is in contact with the bowl the disk beam d is at the bottom of its slide and vice versa at the larger or quick speed radius. The second pair of eccentric wheels 13 and 14 and the second countershaft 15 are geared opposite to the gears 7 and 8 of the first countershaft 9 so that the rollers c are going contrary to the slide, that is to say, the rollers c are revolving at quick speed when the disk beam d is at the bottom of the slide and vice versa when it is at the top. From this it will be evident that the cop is built upon the bare spindle and owing to the disk beam d falling and then rising slowly from the lower limit of its movement and the rollers delivering more yarn owing to their quick motion, the enlarged diameter of the cop bottom is obtained, and vice versa toward the top. The spindle rail n being worked, as before described by the pawl and ratchet wheel from the heart cam lever 11, falls in its slides gradually as the yarn is spun on the spindles, and the spindle rail is raised again to restart spinning a fresh set of cops, by means of a handle placed on the squared end 33 of the spindle of one of the train of wheels 27 (see Fig. 7).

I claim-- The combination of a spindle driven only by the yarn and a pair of gradually descending spindle rails, with a revolving disk, a rising and falling disk rail carrying the said disk which is provided with an arm having an eye at its end, suitable rollers for the delivery of the yarn to be spun and mechanism for revolving the disk and moving the disk rail and spindle rails to form the cop, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN WALKER.
